A blanket-like carbon felt made by pre-oxidation and carbonization of a polyacrylonitrile-based flat felt. Soft texture, lightweight, low heat capacity, good thermal insulation, easy to cut and handle. Resistant to corrosion, high temperature density, and high thermal stability. Long service life and energy efficient. Used in vacuum furnaces, induction furnaces, thermal insulation, energy storage batteries, experimental conductive electrodes, gas adsorption materials, filtration, and stain removal. Technical specifications: Carbon content: 98% or higher Moisture absorption rate: 2% Operating environment: - Air: up to 350°C - Vacuum: up to 1800°C - Inert gas: up to 2650°C Specific resistance (Ω·mm²/m): - Horizontal: 8.2–11.1×10 - Vertical: 11.8–16.8×10 Application areas: 1. Can be used as a flame-retardant material in thermal insulation applications. 2. As a porous material, it can serve as a carrier in chemical industry processes. 3. Suitable as a corrosion-resistant material for inner liners or outer protective layers in composite materials. 4. Widely used as a conductive and absorbent material in aviation, batteries, and electrodes (such as electrode tubes and rods); also applicable in conductive concrete applications. 5. Can be used as an adsorbent for gas and liquid decontamination; in gas processing such as desulfurization and denitrification; high temperature resistance allows use in high-pollution environments like power plants; for liquids, such as oil absorption.
